Hello Spideh7,

Regarding your recent edits to Distillation, I have reverted them for two reasons. Firstly the changes were not encyclopaedic in style, but seemed to be a comment on the article itself, and written as one. Secondly, such modifications require verifiable sources, such as textbooks or journal articles published in peer reviewed journals. Please feel free to re-edit the article, including your citations.
